Question

我正在尝试将 org.apache.http.legacy 库用于asynctask

compileSdkVersion 23
buildToolsVersion "23.0.2"

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.1'
}

我听说在API 23中“org.apache.http”无效所以我试过这个

android {

compileSdkVersion 23
buildToolsVersion '23.0.2'

useLibrary 'org.apache.http.legacy'
}

之后我同步了项目，但没有结果

仍然有很多图书馆没有正确导入

import org.apache.http.Header;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;

当我将API Level 21更改为API Level 23时会出现此问题。因为我想使用API级别23

这是用于解析的方法

    new AsyncHttpClient().get("url",
                      new TextHttpResponseHandler() {

                          @Override
                          public void onStart() {

                          }

                          @Override
                          public void onRetry(int retryNo) {

                          }

                          @Override
                          public void onFailure(int arg0, Header[] arg1,
                                                String response, Throwable arg3) {

                          }

                          @Override
                          public void onSuccess(int arg0, Header[] arg1,
                                                String response) {

                                                }

Answer 1

由于org.apache.http.client.HttpClient已在API级别22中弃用，并且在API级别23中不再受支持，请使用openConnection()。请参阅下面的代码。

URL url = new URL("urlString");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");   
InputStream is = new BufferedInputStream(conn.getInputStream());
String response = org.apache.commons.io.IOUtils.toString(is, "UTF-8");
System.out.println(response);

Answer 2

有人说在Android / sdk / platforms / android-23 / optional中有一个org.apache.http.legacy.jar，

因此我们可以在应用程序lib文件夹中添加该库之后使用useLibrary 'org.apache.http.legacy'

然后同步

Android：org.apache.http异步任务无法正常工作
